SLRGear posted their review of Canon’s new 400mm f/4 DO IS II lens, announced last September for Photokina.

Some excerpts from the review:

On a full-frame body, the Canon 400mm DO II is sharp, though not as tack sharp as the 400mm ƒ/2.8 II

As one would hope from a nearly-$7000 lens, chromatic aberration is very minimal. On both full- and sub-frame cameras, CA was very low

[…] vignetting on this telephoto lens is very, very low.

[…] geometric distortion on the Canon 400mm DO II is practically nonexistent

[…] this large lens is, as they say, “built like a tank”. The build quality is simply impressive […]

From the conclusion:

The Canon EF 400mm ƒ/4 DO IS II USM is a fantastic, professional-level supertelephoto lens. As a significant upgrade optically compared to the original version, the 400mm DO II is an even more attractive option over the heavy, expensive 400mm ƒ/2.8L IS II. For professional and serious wildlife, sports and action photographers who don’t want or need a fast, low-light-friendly ƒ/2.8 supertelephoto prime, the 400mm DO II version offers healthy savings in both cost and weight. Image quality is very good, and the built-in I.S is extremely impressive

The review comes with charts and sample pics.

The Canon 400mm f/4 DO IS II lens is not a budget lens. It sells for around $7000 (B&H Photo | Adorama).

FotoTV on Youtube published an interview with Canon Ambassador Richard Walch about the new EOS 7D Mark II and the likewise new EF 400mm f/4 DO IS II lens.

The EOS 7D Mark II is available for pre-order. In Germany Wex Photographie is accepting pre-orders for the EOS 7D Mark II (€1,699). The new EOS 7D Mark II can be pre-ordered also in the USA. Shipment is expected for November 2014 and orders will be shipped on a first come first serve basis:

Digicame (translated) posted what I am not shy to define as the first reliable rumor on what Canon is going to announce at Photokina 2014. Yes, these lenses are going to be announced at Photokina 2014!

EF-S 24mm f/2.8 STM

EF 24-105mm f/3.5-5.6 IS STM

EF 400mm f/4 DO IS II USM

The EF-S 24mm f/2.8 STM was previously rumored to be an EF lens, instead it is an EF-S lens. Not yet sure if it will be a pancake lens.

The EF 24-105mm f/3.5-5.6 IS STM is aimed at full-frame shooters, who will soon enjoy the benefits of the STM technology for their video shooting. This lens will probably be the next kit lens for the 6D. It will for sure be cheaper than an “L” grade lens. No one saw this lens come.

Finally, the EF 400mm f/4 DO IS II USM lens is the successor to the Canon EF 400mm f/4 DO IS. Several patents filed by Canon in the past pointed in this direction, the latest patent being this one.
